- GFI MailEssentials
- All support environments
SOLUTIONFirstly, ensure there are no port conflicts between MailEssentials and another program:
- Open a command prompt (cmd.exe) and type netstat -abn > c:\gfiports.txt
- Open gfiports.txt in a text editor and search for 8021, 8013 and 8015
- Confirm which service is using this port. If anything other than a GFI MailEssentials service is running on the port, then it confirms that there is a port conflict between the GFI MailEssentials application and a third party application
- Browse to %SystemRoot%\system32\drivers\etc\ and make a backup of the 'hosts' file
- Open this file in a text editor.
- The Hosts file will usually contain the following:
# For example:
# 184.108.40.206 rhino.acme.com # source server
# 220.127.116.11 x.acme.com # x client host
- Change the first localhost entry to 127.0.0.1, so it looks like:
- Save the changes to the Host file
- Open Command Prompt and perform an IISRESET
- The Switchboard and Configuration should now be accessible
The localhost entry was not pointing to the correct address.
